A 5-year-old San Diego boy managed to hack one of the most popular gaming systems in the world, Xbox and has now been acknowledged as a security researcher by Microsoft.

Kristoffer Von Hassel uncovered a vulnerability in Xbox Live's password
system, that would allow someone to log into a Xbox player's account
without their password. Kristoffer's parents noticed he was logging into
his father's Xbox Live account simply by tapping the space bar.

YES, BACKDOOR ENTRY WITH JUST SPACE-BAR

His father noticed that Kristoffer logged in as his Xbox Live account to
play video games that he wasn't meant to be playing and asked how he
had done it.

Kristoffer revealed that by typing in the wrong password and then by
pressing the spacebar, he bypassed the password verification through a
backdoor, and it was pretty simple!

HIS FEELING, "was like yeah!"

5-year-old gamer actually hacked the authentication system of a multi-billion dollar company, and his feeling "was like yeah!", Kristoffer said to local news station KGTV.
